[0002] Initially, lidar was primarily used in atmospheric science to detect atmospheric composition and meteorological parameters. With continuous technological advancements, its applications have expanded to numerous fields such as topographic mapping, forestry surveys, and traffic monitoring. LiDAR determines the distance to a target object by emitting laser pulses and measuring the time it takes for the reflected light to travel. Its high-precision distance measurement capabilities make it a powerful tool for acquiring three-dimensional spatial data. In the field of surveying, traditional methods such as total stations and levels, while highly accurate, suffer from low efficiency and limitations in measuring complex terrain and large areas. The emergence of lidar technology has overcome these shortcomings, enabling the rapid acquisition of large-area three-dimensional topographic data and driving innovation in surveying technology.

[0003] With the rapid development of the geographic information industry, the construction industry, environmental monitoring and other fields, the demand for equipment that can quickly and flexibly perform measurements in complex field environments is increasing. Traditional large-scale lidar measurement systems are usually bulky and heavy, making them inconvenient to use in complex terrains or areas with limited space, such as in the field, mountains, narrow urban streets and other areas.

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a portable lidar photogrammetry device, including,

[0027] The measuring component 100 includes a handle 101, a housing 102 rotatably connected to the end of the handle 101, a spindle 103 movably inserted into the housing 102, and a measuring instrument body 104 mounted on the end of the spindle 103.

[0028] The adjustment assembly 200 includes a fixing member 201 snapped into the middle of the main shaft 103, a connecting rod 202 rotatably mounted on the side wall of the fixing member 201, a lever 203 rotatably mounted on the end of the connecting rod 202, and a limiting block 204 fixedly connected to the end of the housing 102. It also includes a limiting rod 205 rotatably mounted on the side wall of the limiting block 204, with the end of the limiting rod 205 connected to the middle side wall of the limiting block 204 via a rotating shaft.

[0029] The handle 101 facilitates docking with the installation equipment and allows for easy handheld use of the measuring device. A rotatable housing 102 is added to the end of the handle 101. A motor or other components can be added inside the housing 102 to drive its rotation, adjusting the angle of the measuring instrument body 104 mounted on the end of the spindle 103. The spindle 103 is inserted into the middle of the housing 102, allowing for easy adjustment of its extension length along the housing 102, further adjusting the position of the measuring instrument body 104 for better image acquisition of the required measurement area. A fixing member 201 with a connecting rod 202 is added to the side wall of the spindle 103. Rotating the lever 203, in conjunction with the limiting rod 205 mounted on the side wall of the limiting block 204, causes the lever 203 to move the fixing member 201, thereby moving the spindle 103 and adjusting its extension length to accommodate different usage needs.

[0030] Specifically, the adjustment assembly 200 also includes a connector 206 rotatably mounted in the middle of the housing 102, and a pull rod 207 fixedly mounted on the side wall of the connector 206. The end of the pull rod 207 is connected to the end of the lever 203 via a pivot.

[0031] A connector 206 with a pull rod 207 is installed in the middle of the housing 102. The connector 206 is driven to rotate by the drive mechanism, which can work with the pull rod 207 to drive the lever 203 to rotate. In turn, the connecting rod 202 and the fixing member 201 drive the main shaft 103 to extend from the end of the housing 102, thereby adjusting the position of the measuring instrument body 104 to adapt to different usage needs.

[0032] Furthermore, the adjustment assembly 200 also includes a positioning post 208 that is movably inserted into the side wall of the housing 102, with the lower end of the positioning post 208 threadedly connected to the side wall of the connector 206.

[0033] The positioning post 208, which is installed in the middle of the sliding groove on the side wall of the housing 102 and docks with the connector 206, can limit the rotation angle of the connector 206, keep the measuring instrument body 104 from moving within the limited range, and prevent the measuring instrument body 104 from becoming loose.

[0034] Furthermore, the adjustment assembly 200 also includes a spring 209 installed on one side of the upper end of the positioning post 208, with the end of the spring 209 engaged with the side wall of the limiting block 204.

[0035] Among them, a spring 209 connected to the limiting block 204 is added to the end of the positioning post 208. The spring 209 can provide a certain elastic force to the positioning post 208 on the basis of the connection of the limiting block 204, so as to keep the position of the positioning post 208 stable and facilitate the measuring instrument body 104 to return to the original position when the thrust is disconnected.

[0036] Preferably, the adjustment assembly 200 also includes a pull rope 210 mounted on the other side of the upper end of the positioning post 208, with the end of the pull rope 210 snapped into the top of the housing 102.

[0037] A pull rope 210 is installed on the top of the housing 102 and connected to the positioning column 208. Pulling the pull rope 210 can drive the connector 206 to rotate through the positioning column 208, thereby adjusting the position of the measuring instrument body 104. The pull rope 210 can also work with the housing 102 to pull the positioning column 208 and keep the rotation angle of the positioning column 208 stable.

[0038] It should be noted that the adjustment assembly 200 also includes a guide post 211 installed at the end of the lever 203, and a guide groove 212 located at the middle position of the end of the lever 207. The guide post 211 is movably inserted into the middle of the guide groove 212, and the guide post 211 extends to the other side of the lever 203.

[0039] In this design, a guide post 211 is added to the end of the lever 203 to cooperate with the guide groove 212 on the side wall of the pull rod 207. When the pull rod 207 rotates, it will drive the lever 203 with the guide post 211 installed to rotate along the guide groove 212, thereby adjusting the components installed at the end of the measuring equipment.

[0040] Preferably, the adjustment assembly 200 further includes a locking block 213 mounted on the side wall of the spindle 103, the side wall of the locking block 213 being bolted to the side wall of the fixing member 201.

[0041] In this design, a locking block 213 is added to the side wall of the fixing component 201 to connect with the spindle 103. By tightening the matching bolts, the fixing component 201 and the locking block 213 can be locked onto the side wall of the spindle 103, thus maintaining the stability of the fixing component 201.

[0042] In use, the drive mechanism drives the connector 206 to rotate, which in turn drives the lever 203 to rotate with the pull rod 207. With the cooperation of the limit rod 205 installed on the side wall of the limit block 204, the lever 203 will work with the connecting rod 202 to move the fixing part 201, thereby pushing the main shaft 103 to move and adjust the extension length of the main shaft 103 to adapt to the adjustment of the measuring instrument body 104. Then, the pull rope 210 is fixed to the side wall of the housing 102 to prevent the connector 206 from resetting, and photogrammetry operations can be performed.

[0043] In summary, by using the measuring component 100 and the adjusting component 200 together, the equipment can collect data on a large area in a short time, shortening the working time. It does not require direct contact with the object being measured, which has unique advantages for measuring areas or objects that are difficult to reach, dangerous, or sensitive to contact. It is easy to carry to various complex field environments for operation. Its small size and light weight make it easy to transport and move between different terrains. It is not limited by the site and improves the flexibility of the equipment. It can meet the needs of emergency mapping, temporary monitoring and other tasks, and can be used in a variety of complex and changeable operating scenarios.
